F15 Audio Pack v5 for DCS ver. 2.5.6

Version 5: many new things, almost every sound has been changed or tweaked

This mod adds some variety and realism (in my opinion) to jets external sounds. The aim was to recreate the beauty of the passing fighter jet sound as best as possible within the limitation of the DCS sound design. Most of the audios in the mod come from the F15 recordings and only for the eagle they are carefully balanced and edited. Other fighters share some of these audios unintentionally but the mod doesn't change their distinctive engine sounds note.
